The third in the series of yearbooks by the Association of Mathematics Educators in Singapore, Assessment in the Mathematics Classroom is unique as it addresses a focused theme on mathematics education. The objective is to encourage teachers and researchers to include assessment of non-cognitive attributes and to use techniques in addition to paper-and-pencil tests that focus on typical problems.Several renowned international researchers in the field have published their work in the book. The thirteen chapters of the book illustrate evidence-based practices that school teachers and researchers can experiment in their lessons to bring about meaningful learning outcomes. A recurring theme in most chapters is the widely circulated notions of formative assessment and assessment for learning. The book makes a significant contribution towards assessment in mathematics. It is a good resource for research students and a must-read mathematics educators.Contents:Introduction: Assessment Matters (Khoom Yoong Wong & Berinderjeet Kaur)Using a Multi-Dimensional Approach to Understanding to Assess Students' Mathematical Knowledge (Denisse R Thompson & Berinderjeet Kaur)Assessing Problem Solving in the Mathematics Curriculum: A New Approach (Tin Lam Toh, Khiok Seng Quek, Yew Hoong Leong, Jaguthsing Dindyal & Eng Guan Tay)Assessing Conceptual Understanding in Mathematics with Concept Mapping (Haiyue Jin & Khoon Yoong Wong)Using Journal Writing to Empower Learning (Berinderjeet Kaur & Chun Ming Eric Chan)Implementing Alternative Assessment in the Lower Primary Mathematics Classroom (Kai Kow Joseph Yeo)Open-Ended Tasks and Assessment: The Nettle or the Rose (David J Clarke)Using ICT to Improve Assessment (Marja van den Heuvel-Panhuizen, Angeliki Kolovou & Marjolijn Peltenburg)The Assessment for, of and as Learning in Mathematics: The Application of SLOA (Mo Ching Magdalena Mok)Building Bridges Between Large-Scale External Assessment and Mathematics Classrooms: A Japanese Perspective (Yoshinori Shimizu)Errors in Mathematics Assessment Items Written by Pre-Service Teachers (Jaguthsing Dindyal)Affective Assessment in the Mathematics Classroom: A Quick Start (Eng Guan Tay, Khiok Seng Quek & Tin Lam Toh)Implementing Self-Assessment to Develop Reflective Teaching and Learning in Mathematics (Lianghuo Fan)Readership: Mathematics educators, research students and mathematics teachers.
